High Performance Circularly Polarized Antenna Based on Fractal EBG Structure
(2006)
Bao, Xiulong; Ammann, Max; Ruvio, Giuseppe; John, M.
Abstract:
<p>Circularly polarized patch antennas have been widely applied in wireless communication system, global positioning system, etc., because of their low-profile, lightweight, ease of fabrication and low lost [1,2]. To achieve high performance for circularly polarized patch antennas, some new structures were reported in the literature, such as antennas array, stack layer antennas, using periodic structures [3-7], etc. In this paper, a high performance circularly polarized low frequency patch antenna based on the compact fractal high-impedance surface EBG structure has been fabricated and experimented. The measured results show that the proposed circularly polarized patch antenna has good performance in impedance bandwidth, axial ratio (AR) bandwidth, and gain.</p>

Improved Pattern Stability for Monopole Antennas with Ultrawideband Impedance Characteristics
(2003)
Ammann, Max
Abstract:
<p>The requirement of future software defined and reconfigurable radio networks to operate in multiple, wide-ranging, frequency bands places heavy demands on antenna designs. Rather than using antennas tuned at the time of manufacture to operate in certain predefined frequency bands under predefined radio systems, which limits the possibilities of implementing new radio systems on a reconfigurable terminal, a wideband antenna is proposed. The use of a single antenna which can operate over many octaves is very desirable for future wireless communications systems. We discuss the characteristics of the planar monopole, an antenna with wideband properties. The addition of a second planar element orthogonal to a planar monopole improves the radiation pattern stability without degrading the ultrawideband impedance characteristics.</p>

Wideband Directional Base-station Antenna with Dual-linear and Circular-polarization Capabilities
(2006)
Lerma, Francisco; John, M.; Ruvio, Giuseppe; Ammann, Max; Herscovici, N.
Abstract:
<p>A crossed-dipole antenna providing polarization diversity is presented. The antenna which employs a planar reflector yields high directivity and good isolation between ports over a wide impedance bandwidth, suitable for polarization-agile wireless base-station use. The dipole wing shape is optimised, which yields the wide bandwidth. Matching is achieved using a quarter-wave balanced-to-unbalanced section which also improves the port-to-port isolation. Radiation characteristics for linear and circular polarizations are presented</p>

Identification and PID control of time-delayed processes
(2003)
Kealy, Tony, (Thesis)
Abstract:
<p>This research was conducted primarily to investigate a selection of known methods for the identification of a mathematical model for processes with an inherent time delay, and subsequently, use the parameters of the identified model to regulate the processes via the PI/PID control strategy. The research examines the level of difficulty in performing or sanctioning different system identification methods in order to re-tune the controller. The process model identification methods are carried out on both simulated and real processes in the first part of the research. The selected parametric identification methods are chosen because they encompass open- and closed- loop techniques, first –order-plus-dead-time and second-order-plus-dead-time process models and both frequency- and time-domain identification methods. The second part of the research considers the PI/PID control strategy to regulate the processes identified using the aforementioned process model identification meth...

Extraction of fingerprint from regular expression for efficient prefiltering
(2009)
Wang, Xiaofei; Jiang, Junchen; Lin, Wei; Tang, Yi; Wang, Xiaojun; Liu, Bin
Abstract:
Deep packet inspection at high speed has become extremely important due to its application in a wide range of network applications, such as network security and network monitoring. Network intrusion detection system (NIDS) uses a collection of signatures of known security threats and viruses to scan the payload of each packet. Signatures are often specified in the form of regular expressions (regex), called patterns, which are traditionally implemented as finite automata. Deterministic finite automata (DFA) is fast, but requires prohibitive amounts of memory which limits their practical use. Instead of matching an incoming packet with each individual regex in a ruleset, we match the packet with a fixed substring, called fingerprint, of a regex first. Fixed string matching is faster and consumes less energy than regex matching. The fact is that if a packet does not match with the fingerprint of a regex, it will not match the regex itself. So fingerprints can be used in a prefilter en...

Investigation of the Slow- and Fast-Light Effect on the Basis of Stimulated Brillouin Scattering for Application in Optical Communication and Information Systems.
(2010)
Henker, Ronny, (Thesis)
Abstract:
<p>In today's information age demand for ultra-fast information transfer with ultra-high bandwidths has reached extraordinary levels. Hence, the transmission in the future internet-backbone will be increasingly constrained in the network nodes. At the same time, the power consumption of the network systems will increase to unsustainable levels. To overcome these constraints power-ecient photonic networks which provide ultra-fast all-optical switching and routing are essential. Nowadays, optical signal processing and switching can be implemented relatively easily. However, the realization of optical bu ers and short-term memories is still an unsolved challenge. The slow- and fast-light e ect has been investigated as one solution for the optical bu ering over the last few years. It means the slowing down and acceleration of the group velocity of light pulses in a medium. To realize this, many di erent methods and material systems have been developed but due to its signi can...

Abstract:
The aim of this project is to analyse the Group Processing Approach (the “GPA”) to renewable generator grid connections, and in particular the Gate 3 process which is the latest round of the GPA that is currently being implemented in the Republic of Ireland, to determine if it is the most effective approach for connecting new renewable generation. Gate 3 is the third series of the GPA for connecting renewable generation to the Irish Electricity grid where applications are processed in groups or batches. The size of the Gate 3 has bee capped at 3,900MW with applicants being selected based on application date order and applicants will be granted firm access to the grid in order of the anticipated speed with which the required deep transmission reinforcement works can be completed. The author firstly provides a high-level overview of the technical considerations for connecting vast amounts of dispersed wind energy to the national grid, the development of wind energy in Ireland and th...

Use of a Single-Multiple-Single-Mode Fiber Filter for Interrogating Fiber Bragg Grating Strain Sensors with Dynamic Temperature Compensation
(2009)
Wu, Qiang; Schwarzbacher, Andreas; Semenova, Yuliya; Farrell, Gerald
Abstract:
An interrogation technique for fiber Bragg grating (FBG) strain sensors with dynamic temperature compensation using a single-multiple-single-mode (SMS) fiber filter as a temperature compensating element is presented. Experimental results show that this technique offers a resolution of better than 3:4 με for strain measurements in the range from 0 to 1667 με, and the temperature induced error is as low as 34 με in the temperature range from 10 to 60 °C. The temperature induced error could be further reduced if the temperature sensitivity (the rate of temperature induced wavelength shift) of the SMS filter was closer to that of the FBG sensor. This can be achieved by selecting a multimode fiber for the SMS filter with appropriate parameters. The proposed technique can be modified for simultaneous measurements of strain and temperature with an experimentally achieved resolution of better than 1 °C. © 2009 Optical Society of America Applied Optics, Vol.48, no. 29, p.5451

Abstract:
In this paper the design and rapid prototyping of networked A/V CE appliances is described. Practical implementations of three types of appliance are described: (i) a streaming A/V server; (ii) a streaming A/V client device and (iii) a networked A/V transcoding device. It is shown how these devices can be used to provide both a robust and scalable multimedia solution, which can be adapted for use in many applications. A review of known techniques for realizing the required multimedia functionality is given and some methods of reducing the development time of these prototypes are also discussed.

Wideband dynamic numerical model of a tapered buried ridge stripe semiconductor optical amplifier gate
(2011)
Connelly, Michael J.
Abstract:
A wideband dynamic numerical model of a tapered buried ridge stripe semiconductor optical amplifier is described. The model is based on a carrier density rate equation and a set of travelling-wave equations describing the amplified signal fields and spontaneous emission photon rates. These equations are solved in time and space using a computationally efficient numerical algorithm. The model is used to predict the switching properties of an optical gate. A simple equivalent circuit model of the gate, including package parasitics, is derived that can be used in conventional electrical circuit simulation tools.

Deployment and Characterisation of a Telescopic Boom for Sounding Rockets

Abstract:
<p>In any sounding rocket, volume and mass are at a premium. Payload designers strive towards smaller, lighter and cheaper mechanisms which can achieve the same goals. This project aims to reduce the mass and volume for probe deployment booms and their deployment mechanisms. An experiment (Telescobe) to test a low cost novel method of boom deployment using telescopic carbon fibre poles was developed. A custom camera measurement system was also developed to measure boom length and harmonic deflection. This experiment was flown onboard the REXUS 9 sounding rocket [1] in February 2011 from Esrange space centre, Sweden. The experiment functioned as expected in all pre-flight tests. However, an unexpected malfunction in the experiment hatch door was experienced during flight which prevented the boom from being extended through the hatch. Despite this, it was found that the carbon fibre sections, all mechanisms and hardware, survived the flight and functioned as expected as far as p...

Abstract:
Making use of a class of 2D statistical face models known as active appearance models (AAMs), we investigate a technique for generating real-time animated avatars suitable for video gaming. We consider here a number of improvements of these models in order to make them more robust to varying environmental conditions, as well as to reduce the computational load such that to become adapted for real-time implementations.

A Novel Telescopic Boom Deployment System for Use in Upper Atmosphere Research
(2010)
Wylie, Mark; Duffy, Paul; Vather, Dinesh; Keegan, Johnalan; Curran, Stephen
Abstract:
<p>Typical measurement probe deployment systems on sounding rockets employ hinged booms which extend the probes away from the rocket. This configuration often has a significant mass and may require a considerable amount of the rocket’s valuable payload volume. In an effort to reduce both mass and volume, the DIT Space Research Group have designed a light weight carbon fibre telescopic boom system, compatible with measurement probes commonly used in upper atmosphere research. Our design has been selected to be tested on a suborbital space flight onboard the REXUS 9 sounding rocket in March 2011. The purpose of this test is to characterise the boom system in-situ and increase its Technology Readiness Level (TRL). The system is capable of deploying a boom with a mock electromagnetic field (E-field) probe to a length of 1.63m ±0.5%. The mock probe will be attached to the distal end of the boom and will house six LEDs, which emit light at a wavelength of 620 nm. A filtered camera m...

Applying Computational Models of Spatial Prepositions to Visually Situated Dialog
(2009)
Kelleher, John; Costello, Fintan
Abstract:
<p>This article describes the application of computational models of spatial prepositions to visually situated dialog systems. In these dialogs, spatial prepositions are important because people often use them to refer to entities in the visual context of a dialog. We first describe a generic architecture for a visually situated dialog system and highlight the interactions between the spatial cognition module, which provides the interface to the models of prepositional semantics, and the other components in the architecture. Following this, we present two new computational models of topological and projective spatial prepositions. The main novelty within these models is the fact that they account for the contextual effect which other distractor objects in a visual scene can have on the region described by a given preposition. We next present psycholinguistic tests evaluating our approach to distractor interference on prepositional semantics, and illustrate how these models are...

Effects of Lline Rate on vVideo QoS over Wireless Networks: an Experimental Approach
(2008)
Wallace, Stuart; Davis, Mark
Abstract:
<p>Video streaming over Wireless Local Area Networks (WLANS) is becoming an increasingly popular service. However, end user OoS is highly influenced by many factors. These include the video codec used, the packetization scheme, error concealment and correction techniques, the complexity of the video, propagation losses, and the line rate. In this paper the effect of the line rate on the capacity of the network when streaming multimedia content is analyzed experimentally. It is shown that as the line rate decreases the bandwidth load of the video stream dramatically increases leading to poor QoS at the client side. As automatic line rate adaptation schemes are typically employed in the majority of WLAN adapters, clients have no control over the line rate of their connection and consequently can suffer from a poor QoS for their video streaming services.</p>

Investigation of Across-layer Modification to the DSR Routing Protocol in Wireless Mesh Networks
(2008)
Ramadhan, Mustafa; Davis, Mark
Abstract:
<p>This work introduces a cross-layer modification to the DSR protocol that increases the global throughput in wireless mesh networks. In our modified DSR protocol we have introduced the Access Efficiency metric as an alternative to the hop-count metric in order to improve the route selection mechanism. The selected path in the route selection mechanism is identified by choosing the path with the highest minimum Access Efficiency value. We have employed the OPNET modeller as a simulator to examine two different patterns of traffic for a series of randomly generated network topologies. Each topology was simulated twice. One simulation used the original DSR algorithm while the other utilised the modified DSR algorithm. The average throughput was recorded for each run and the percentage improvement for the particular topology was calculated. Our results demonstrate that a significant increase in the global throughput of the networks can be achieved by implementing our modified DS...

A secure and efficient micropayment solution for online gaming
(2009)
Grzonkowski, Slawomir; Corcoran, Peter M.
Abstract:
An innovative micropayment solution is proposed which incorporates both distributed security and social networking features. This has significant potential to impact on both the provision of new services and community features in online massive multiplayer online role-playing gaming (MMORPG) worlds. Initial feasibility implementation and testing of the micropayments system on both desktop and handheld device clients is presented. The system is well suited to gaming applications and our preliminary studies indicate the practical feasibility of integrating it within an operational MMORPG architecture.

Situating Spatial Templates for Human-Robot Interaction

Abstract:
People often refer to objects by describing the object's spatial location relative to another object. Due to their ubiquity in situated discourse, the ability to use 'locative expressions' is fundamental to human-robot dialogue systems. A key component of this ability are computational models of spatial term semantics. These models bridge the grounding gap between spatial language and sensor data. Within the Artificial Intelligence and Robotics communities, spatial template based accounts, such as the Attention Vector Sum model (Regier and Carlson, 2001), have found considerable application in mediating situated human-machine communication (Gorniak, 2004; Brenner et a., 2007; Kelleher and Costello, 2009). Through empirical validation and computational application these template based models have proven their usefulness. We argue, however, that these models ignore important contextual features; resulting in their over-generalization and failure to account for actual us...
